The Financial Post reports in its Saturday edition that Canadian oil producers remain steadfastly optimistic, despite the current glut. A Bloomberg dispatch to the Post says that even as prices dipped to new lows on Thursday, some companies including Suncor and Canadian Natural Resources see reasons for optimism. Enbridge's Line 3 pipeline is scheduled to be expanded and more oil is moving by rail. For now, however, some producers are choosing to cut output rather than sell at current regional prices. "Demand for these products is coming up," Steven Williams, Suncor chief executive officer, said in a conference call Thursday. "Rail movements are starting to ratchet up, and of course, we had good news this last week about Line 3 progressing." Canadian crude prices collapsed last month as a surge of new oil sands production and output from the shale formations of the Montney and Duvernay encountered pipeline bottlenecks and reduced U.S. demand amid refinery maintenance. Western Canada Select fell to a discount of more than $50 a barrel to West Texas Intermediate futures last month. Light Edmonton mixed sweet reached its widest point since 2014 Thursday, while light synthetic crude fell to its widest since 2006.
